<h1>Local Discovery Server (LDS) Overview</h1>
<p>The <a href="http://www.opcfoundation.org/ua/part4"><?rh-udv_start name="UaSpec04" ?>UA Specifications Part 4 - Services (http://www.opcfoundation.org/ua/part4)<?rh-udv_end ?></a> 
 and <a href="http://www.opcfoundation.org/ua/part12"><?rh-udv_start name="UaSpec12" ?>UA Specifications Part 12 - Discovery (http://www.opcfoundation.org/ua/part12)<?rh-udv_end ?></a>&#160;describe 
 the purpose and operations of a local discovery server. The short explanation 
 is that this type of server merely provides a list of available OPC UA 
 applications to any application that queries it; where each application 
 is running and registering (frequently) with the LDS.</p>
<p>The LDS that is provided within this package runs as an unattended Windows 
 background service:</p>
